Regardless of how it is implemented, I have another gripe with this helper: the way it must be used requires a process: $(test_out_to_path $foo) And looking through this patch series, I see a gazillion of *new* process substitutions $(test_something...) and $(basename $whatever). Can't we do something about it? -- Hannes
